Tongue-tie (ankyloglossia) is a condition present at birth that restricts the tongue's range of motion.

With tongue-tie, an unusually short, thick or tight band of tissue (lingual frenulum) tethers the bottom of the tongue's tip to the floor of the mouth. A person who has tongue-tie might have difficulty sticking out his or her tongue. Tongue-tie can also affect the way a child eats, speaks and swallows, as well as interfere with breast-feeding.

Sometimes tongue-tie may not cause problems. Some cases may require a simple surgical procedure for correction.

Signs and symptoms of tongue-tie include:

Difficulty lifting the tongue to the upper teeth or moving the tongue from side to side

Trouble sticking out the tongue past the lower front teeth

A tongue that appears notched or heart shaped when stuck out

When to see a doctor

See a doctor if:

Your baby has signs of tongue-tie that cause problems, such as having trouble breast-feeding

Your older child complains of tongue problems that interfere with eating, speaking or reaching the back teeth

You're bothered by your own symptoms of tongue-tie

Typically, the lingual frenulum separates before birth, allowing the tongue free range of motion. With tongue-tie, the lingual frenulum remains attached to the bottom of the tongue. Why this happens is largely unknown, although some cases of tongue-tie have been associated with certain genetic factors.

Although tongue-tie can affect anyone, it's more common in boys than girls. Tongue-tie sometimes runs in families.

Tongue-tie can affect a baby's oral development, as well as the way he or she eats, speaks and swallows.

For example, tongue-tie can lead to:

Breast-feeding problems. Breast-feeding requires a baby to keep his or her tongue over the lower gum while sucking. If unable to move the tongue or keep it in the right position, the baby might chew instead of suck on the nipple. This can cause significant nipple pain and interfere with a baby's ability to get breast milk. Ultimately, poor breast-feeding can lead to inadequate nutrition and failure to thrive.

Speech difficulties. Tongue-tie can interfere with the ability to make certain sounds — such as "t," "d," "z," "s," "th" and "l." It can be especially challenging to roll an "r."

Poor oral hygiene. For an older child or adult, tongue-tie can make it difficult to sweep food debris from the teeth. This can contribute to tooth decay and inflammation of the gums (gingivitis). Tongue-tie can also lead to the formation of a gap or space between the two bottom front teeth.

Challenges with other oral activities. Tongue-tie can interfere with activities such as licking an ice cream cone, licking the lips, kissing or playing a wind instrument.

Here's some information to help you get ready for your appointment and know what to expect from your doctor.

What you can do

Prepare a list of questions to help you make the most of your time with the doctor. For tongue-tie, you might ask:

How severe is the tongue-tie?

Is treatment needed?

What are the treatment options?

Should I consider surgical correction?

What's involved in surgical correction? What are the risks?

Is anesthesia necessary?

Will surgical correction improve my child's ability to get more milk during breast-feeding?

Can the procedure be done in the office or hospital nursery?

Do I need to consult an ear, nose and throat doctor or other specialist?

What to expect from your doctor

The doctor is likely to ask you a number of questions. For example:

If your infant has tongue-tie, are you having trouble breast-feeding him or her?

If your older child has tongue-tie, is he or she having trouble making certain sounds or taking care of his or her teeth? Is a gap developing between your child's two bottom front teeth?

If you have tongue-tie, are you concerned about activities you're not able to do because of limited tongue movement?

Tongue-tie is typically diagnosed during a physical exam. For infants, the doctor might use a screening tool to score various aspects of the tongue's appearance and ability to move.

Treatment for tongue-tie is controversial. Some doctors and lactation consultants recommend correcting it right away — even before a newborn is discharged from the hospital. Others prefer to take a wait-and-see approach.

The lingual frenulum may loosen over time, resolving tongue-tie. In other cases, tongue-tie persists without causing problems. In some cases, surgical treatment may be required.

Surgical treatment of tongue-tie may be done for infants, children or adults if tongue-tie causes problems. Surgical procedures are frenotomy or frenuloplasty.

Frenotomy

A simple surgical procedure called a frenotomy can be done with or without anesthesia in the hospital nursery or doctor's office.

The doctor examines the lingual frenulum and then uses sterile scissors to snip the frenulum free. The procedure is quick and discomfort is minimal since there are few nerve endings or blood vessels in the lingual frenulum.

If any bleeding occurs, it's likely to be only a drop or two of blood. After the procedure, a baby can breast-feed immediately.

Complications of frenotomy are rare — but could include bleeding or infection, or damage to the tongue or salivary glands. It's also possible for the frenulum to reattach to the base of the tongue.

Frenuloplasty

A more extensive procedure known as a frenuloplasty might be recommended if additional repair is needed or the lingual frenulum is too thick for frenotomy.

Frenuloplasty is done under general anesthesia with surgical tools. After the frenulum is released, the wound is usually closed with sutures that absorb on their own as the tongue heals.

Possible complications of frenuloplasty are similar to frenotomy and rare — bleeding or infection, or damage to the tongue or salivary glands. Scarring is possible due to the more extensive nature of the procedure, as are reactions to anesthesia.

After frenuloplasty, tongue exercises might be recommended to enhance tongue movement and reduce the potential for scarring.
